Impurity spectrum
Witryna30 gru 2024 · Spectrum of a single impurity in the unitary Bose gas is calculated. Abstract. By using simple and efficient method we discuss properties of a single impurity immersed in three-dimensional Bose gas with the interaction between particles tuned to unitary limit. Particularly, adopting the mean-field-like approximation we present the … Witryna15 gru 1994 · Most chemical vapor deposited (CVD) diamond films contain impurities which increase their optical absorption in the regions of desired transparency. This paper examines the incorporation of these impurities, intentional or otherwise, and their effect on the IR absorption of CVD diamond, particularly in the 8–12 and 3–5 μm regions.
